Abstract
Background: Hemodialysis patients are more prone to Hepatitis C Virus (HCV) infection due to the need for long-term hemodialysis and blood transfusions. Objectives: The present study aimed to determine the HCV infection burden, viral load, and genotype pattern in hemodialysis patients referred to a research center from 2011 to 2018. Methods: Among 131 hemodialysis patients with suspected HCV infection, referred to Prof. Alborzi Clinical Microbiology Research Center, Shiraz, Iran, from 2011 to 2018, the HCV rate was assessed with the enzyme-linked immunosorbent assay and the HCV RNA load and genotypes by one-step TaqMan real-time PCR. Results: The prevalence of HCV-Ab positivity was 29% among hemodialysis patients, of whom 21 (57%) were HCV RNA-positive. In the rest of the hemodialysis patients who were HCV-Ab-negative, the HCV RNA was detected in five (12%) patients. Genotype 3 (Gt-3) was the most prevalent one detected in 50% of the patients whose genotypes were determined. Also, the HCV viral load in HCV-seropositive patients was generally higher than that in HCV-seronegative ones. Conclusions: This study showed that high HCV infection and different genotype patterns among hemodialysis patients compared to the general population are the main predictors of HCV infection, which indicates healthcare facility transmission because of inappropriate infection management practices.

Abstract
Background Hepatitis C virus (HCV) infection is one of the most common bloodborne viral infections reported in Pakistan. Frequent dialysis treatment of hemodialysis patients exposes them to a high risk of HCV infection. The main purpose of this paper is to quantify the prevalence of HCV in hemodialysis patients through a systematic review and meta-analysis. Methods We systematically searched PubMed, Medline, EMBASE, Pakistani Journals Online and Web of Science to identify studies published between 1 January 1995 and 30 October 2019, reporting on the prevalence of HCV infection in hemodialysis patients. Meta-analysis was performed using a random-effects model to obtain pooled estimates. A funnel plot was used in conjunction with Egger’s regression test for asymmetry and to assess publication bias. Meta-regression and subgroup analyses were used to identify potential sources of heterogeneity among the included studies. This review was registered on PROSPERO (registration number CRD42019159345). Results Out of 248 potential studies, 19 studies involving 3446 hemodialysis patients were included in the meta-analysis. The pooled prevalence of HCV in hemodialysis patients in Pakistan was 32.33% (95% CI: 25.73–39.30; I2 = 94.3%, p < 0.01). The subgroup analysis showed that the prevalence of HCV among hemodialysis patients in Punjab was significantly higher (37.52%; 95% CI: 26.66–49.03; I2 = 94.5, p < 0.01) than 34.42% (95% CI: 14.95–57.05; I2 = 91.3%, p < 0.01) in Baluchistan, 27.11% (95% CI: 15.81–40.12; I2 = 94.5, p < 0.01) in Sindh and 22.61% (95% CI: 17.45–28.2; I2 = 78.6, p < 0.0117) in Khyber Pukhtoonkhuwa. Conclusions In this study, we found a high prevalence (32.33%) of HCV infection in hemodialysis patients in Pakistan. Clinically, hemodialysis patients require more attention and resources than the general population. Preventive interventions are urgently needed to decrease the high risk of HCV infection in hemodialysis patients in Pakistan.

Abstract
BACKGROUND Hepatitis C virus (HCV) is a major cause of liver disease and a potential cause of substantial morbidity and mortality. This study aims to provide a comprehensive evidence on HCV Infection in Iranian hemodialysis (HD) patients we conducted a systematic review. MATERIALS AND METHODS In this systematic review and meta-analysis, through a comprehensive search of literature until January of 2016, we estimated the pooled prevalence of hepatitis C infection in Iranian HD patients. Using Medical Subject Headings terms, Emtree, and related equal Persian key words for Iranian databases and also international databases of PubMed and NLM Gateway (for MEDLINE), and SCOPUS. Interest outcome of HCV infection prevalence was confirmed based on positive hepatitis B surface antigen of blood samples. Random effect meta-analysis was used to estimate pooled prevalence of HCV infection in Iranian HD patients, date and language, HD patients, in adult HD patients, Institute of Scientific Information, Iran-doc, irrespective of age, living in Iran. Searches run through main domestic databanks of Iran-Medex, renal transplantation, Scientific Information Database, the relevant literature-searched concentrating on HCV infection. RESULTS Through searching steps, 305 publications were found from them following the excluding duplicates and overlapping studies 54 studies relevant to HCV prevalence in Iranian HD zcxw patients, with number of 23921 participants, remained in our analyses. The overall results of test of heterogeneity demonstrate sever heterogeneity between reported prevalence (I2 = 96.62%, Chi-square = 1566, P < 0.001). Due to sever heterogeneity results of random effect meta-analysis showed that the estimated pooled prevalence was 11% (95% confidence interval [CI] =10%-13%). The pooled prevalence base on polymerase-chain reaction, recombinant immunoblot assay, and enzyme-Linked Immunosorbant Antibody method were 11% (95% CI = 6%-15%), 9% (95% CI = 5-13) and 12% (95% CI = 10-14), respectively. In line with previous studies, the present finding shows the significant variation in the rate of HCV in dialysis units among the regions in Iran. CONCLUSION Present paper is the comprehensive updated systematic review on HCV prevalence in the Iranian HD patients. Our findings provide the reliable evidence for promotion of policies and interventional programs.

Abstract
AIM To determine hepatitis C virus (HCV) infection prevalence in each country of the Middle-East and the overall prevalence of the region. METHODS In this systematic review, we gathered all documents related to HCV infection prevalence among hemodialysis patients in 17 middle-east countries from April 2006 to March 2016. We selected only cross-sectional studies that had proper sampling and measurement methods as well as a valid statistical analysis. RESULTS After screening of 7311 documents, 56 studies were selected reporting the prevalence of HCV infection among hemodialysis patients from 10 countries of the region. Seven countries including United Arab Emirates, Afghanistan, Qatar, Bahrain, Kuwait, Oman, Israel, and Cyprus did not have any relevant document; thus, their latest reports were just mentioned. We performed the meta-analysis and determined the prevalence rates for each country as well as the whole region. The overall HCV infection prevalence among hemodialysis patients in the region was reported to be 25.3%; Egypt and Syria had the highest reported rates while Iran and Lebanon had the lowest. Further investigations are still needed to provide more reliable databases, find main risk factors, and to improve diagnosis and treatment plans, particularly in higher prevalent countries. CONCLUSION Controlling the prevalence and improving the management methods of HCV infection among hemodialysis patients are of a great concern in the Middle-East region.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection causes significant morbidity and mortality in patients of end stage renal disease (ESRD) on haemodialysis (HD). Stringent screening methods can help in its early diagnosis. OBJECTIVE The study addresses the utility of real-time quantitative polymerase chain reaction (RQ-PCR) in the diagnosis and monitoring of HCV infection especially on seronegative and normal serum alanine aminotransferase (ALT) HD patients. MATERIAL AND METHODS This retrospective study was carried out from January 2010 to December 2012. Patients of ESRD on maintenance HD and on whom all the three assays HCV antibody serology, PCR and ALT were done were included in the study (n=123). Group 1 (n=57), comprised of patients with negative serology and normal ALT, and Group 2 (n=66), had either raised ALT and or a positive or equivocal serology. RESULTS Out of the 123 cases studied, HCV serology was positive in 36.5% (45), ALT raised in 18.6% (23) and PCR positive in 67.4% (83) cases. PCR positivity was significantly higher than serology and raised ALT. Group 2 had a significantly higher PCR positivity than Group 1 (P=0.0004), but 50.9% patients of Group 1, were also PCR positive and 69% of them had a high viral count of >8×10(5) IU/ml at the time of detection. CONCLUSION Regular routine screening of HCV by RQ-PCR in ESRD patients can help in early diagnosis of HCV infection in patients with low index of suspicion.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection is a common cause of acute and chronic hepatitis among the hemodialysis population. To prevent cross infection between hemodialysis patients during the hemodialysis procedure, routine screening of anti-HCV antibody is recommended. However, a reactive anti-HCV EIA test is not equal to active HCV infection. An expensive RT-PCR study is required to confirm HCV viremia. This will significantly increase the cost burden because payment for each hemodialysis treatment is very low in Taiwan. Thus, it is useful to identify parameters that could predict HCV viremia among anti-HCV-reactive patients. In this study, we examined the usefulness of signal-to-cut (S/CO) ratio of anti-HCV antibody in discriminating HCV viremia from non-viremia among the anti-HCV-reactive hemodialysis population. MATERIALS AND METHODS In a cross-sectional measurement of anti-HCV antibody among 369 chronic hemodialysis patients, 44 showed reactive and 9 grey zone reaction for anti-HCV. These 53 patients underwent further blood tests for the measurement of AST, ALT and HCV RNA (by RT-PCR). The results of RT-PCR were used as a dependent variable. Then, S/CO ratios of anti-HCV, serum AST, ALT levels, age and duration of hemodialysis were used as independent variables to undergo ROC curve and logistic regression analysis. RESULTS Thirty-six of the 53 reactive and grey zone patients were positive for HCV RNA in the RT-PCR study. Patients who were positive for HCV RNA had a higher S/CO ratio (p < 0.01), higher AST and ALT levels (p < 0.01), and longer duration on hemodialysis (p < 0.05) than those negative for HCV RNA. Logistic regression revealed that only S/CO ratio was a significant predictor for HCV viremia (p = 0.004). ROC curve analysis showed that S/CO ratio had a highest area under curve (0.967, p < 0.001), followed by ALT (0.826, p < 0.001), AST (0.778, p = 0.001), duration on hemodialysis (0.606, p = 0.215) and age (0.426, p = 0.386) in discriminating HCV viremia from non-viremia. Using a cutoff S/CO ratio of 65, we can confirm HCV viremia with a diagnostic specificity of 100%, sensitivity of 80.1% and positive predictive value of 100%. CONCLUSION S/CO ratio is a useful indicator in predicting HCV viremia among anti-HCV-reactive hemodialysis patients. Patients with an S/CO ratio >65 can be regarded as those with active HCV infection. Alternatively, patients with reactive anti-HCV but with an S/CO ratio <65 should receive further RT-PCR test.

Abstract
The prevalence of hepatitis C virus (HCV) infection in patients on maintenance hemodialysis (MHD) is relatively higher than those without MHD. Chronic HCV infection detrimentally affects the life quality and expectancy, leads to renal transplant rejection, and increases the mortality of MHD patients. With the application of erythropoietin to improve uremic anemia and avoid blood transfusion, the new HCV infections during MHD in recent years are mainly caused by the lack of stringent universal precautions. Strict implementation of universal precautions for HCV transmission has led to markedly decreased HCV infections in many hemodialysis units, but physicians still should be alert for the anti-HCV negative HCV infection and occult HCV infection in MHD patients. Standard interferon alpha and pegylated interferon alpha monotherapies at a reduced dose are currently the main treatment strategies for MHD patients with active HCV replication, but how to increase the sustained virological response and decrease the side effects is the key problem. IFNα-free treatments with two or three direct-acting antivirals without ribavirin in MHD patients are waiting for future investigations.

Abstract
Nosocomial transmission of HCV is a concern in haemodialysis (HD) units worldwide. Diagnosis of HCV infection among dialysis patients is currently based on the detection of anti HCV antibodies by ELISA, and is confirmed by HCV RNA. The average window period between HCV infection and seroconversion with new generations of HCV antibody tests remains approximately 70 days with more prolonged period among dialysis patients. In this study we assessed the diagnostic performance of an immunoassay designed for simultaneous detection of anti HCV antibodies and core antigen in one step in comparison to qualitative RT-PCR and anti HCV antibodies detection test among Egyptian haemodialysis patients. The studied patients were 39 chronic renal failure patients on maintenance haemodialysis. The results obtained in the present study revealed HCV infection of 56.4%. Combined Ag/Ab test detected 3 out of the 4 anti-HCV negative viraemic patients who were in the window period. The sensitivity, specificity and accuracy of the test were higher than that of anti HCV antibodies detection test (95.45%, 94.1% and 94.87% versus 81.8%, 88.23% and 84.6%) and they were raised to 100% on combining its positivity with liver enzymes elevation results. Therefore, this simple combined Ag/Ab test can be applied for early detection of HCV infection during window period among HD patients as an alternative to HCV RNA detection.

Abstract
Aim High prevalence of Hepatitis C virus (HCV) has been reported among the dialysis patients throughout the world. No serious efforts were taken to investigate HCV in patients undergoing hemodialysis (HD) treatment who are at great increased risk to HCV. HCV genotypes are important in the study of epidemiology, pathogenesis and reaction to antiviral therapy. This study was performed to investigate the prevalence of active HCV infection, HCV genotypes and to assess risk factors associated with HCV genotype infection in HD patients of Khyber Pakhtunkhwa as well as comparing this prevalence data with past studies in Pakistan. Methods Polymerase chain reaction was performed for HCV RNA detection and genotyping in 384 HD patients. The data obtained was compared with available past studies from Pakistan. Results Anti HCV antibodies were observed in 112 (29.2%), of whom 90 (80.4%) were HCV RNA positive. In rest of the anti HCV negative patients, HCV RNA was detected in 16 (5.9%) patients. The dominant HCV genotypes in HCV infected HD patients were found to be 3a (n = 36), 3b (n = 20), 1a (n = 16), 2a (n = 10), 2b (n = 2), 1b (n = 4), 4a (n = 2), untypeable (n = 10) and mixed (n = 12) genotype. Conclusion This study suggesting that i) the prevalence of HCV does not differentiate between past and present infection and continued to be elevated ii) HD patients may be a risk for HCV due to the involvement of multiple routes of infections especially poor blood screening of transfused blood and low standard of dialysis procedures in Pakistan and iii) need to apply infection control practice.

Abstract
Chronic Hepatitis C (HCV) infection is an important cause of morbidity and mortality in patients with end-stage renal disease. Renal transplantation confers a survival advantage in HCV-infected patients. Renal transplant candidates with serologic evidence of HCV infection should undergo a liver biopsy to assess for fibrosis and cirrhosis. Patients with Metavir fibrosis score ≤3 and compensated cirrhosis should be evaluated for interferon-based therapy. Achievement of sustained virological response (SVR) may reduce the risks for both posttransplantation hepatic and extrahepatic complications such as de novo or recurrent glomerulonephritis associated with HCV. Patients who cannot achieve SVR and have no live kidney donor may be considered for HCV-positive kidneys. Interferon should be avoided after kidney transplant except for treatment of life-threatening liver injury, such as fibrosing cholestatic hepatitis. Early detection, prevention, and treatment of complications due to chronic HCV infection may improve the outcomes of kidney transplant recipients with chronic HCV infection.

Abstract
The risk of hepatitis B and C transmission in health care settings has generated considerable attention within the legal system. This article begins with an overview of the relevant sources of law and then explores legal duties and liability arising from two major categories of risk: occupational risks to health care providers and health care-associated risks to patients and other third parties.
